[Info-vax] Transferring file to VMS emulated in SIMH

[zibree at gmail.com]

Maybe is better if I explain better:

What I have done:

RUN SIMH and installed VMS 5.5-2 from ISO CD.
INSTALLED all HOBBYIST LICENSES

Now I wat to install system software like MULTINET (which I already acquired) and many others.

The problem:
Incredibly enough nobody made a utility to transfer files from the host running SIMH to the guest running VMS.

I then downloaded http://vms.process.com/ftp/tcpware/vms/unzip-vax.exe

Then I used https://github.com/simh/simtools/blob/master/converters/mksimtape/mksimtape.c

And I did:
./mksimtape unzip-vax.exe >unzip.tap

In VMS I mounted the tape with:
$ mount/nolab MUA0:
%MOUNT-I-WRITELOCK, volume is write locked
%MOUNT-I-MOUNTED,  mounted on _MUA0:
$ copy mua0:unzip.exe unzip.exe
$ run unzip.exe
%DCL-W-ACTIMAGE, error activating image UNZIP.EXE
-CLI-E-IMGNAME, image file DUA0:[SYS0.][000000]UNZIP.EXE;2
-IMGACT-F-IMG_SIZ, image header descriptor length is invalid

but the file seems to be there:

Dump of file SYS$SYSROOT:[000000]UNZIP.EXE;2 on 29-DEC-2018 11:35:20.69

since VMS 5-5-2 is a clean install I have only MACRO assembler and not much more.

Any ideas? I think the solution is simple but I don't touch a "vax" since 30 years... and I am not only rusty... I remember near to nothing :/
